i thought holy crap till i saw you said gtech

yeah thats about right the mph is off because its an instaneous speed based upon calculation wihtin the gtech. distance over time.... the track measures an average of speed over the last 60 feet or so thast why its less than gtech. the 14.87 is pretty good, my friend just got back from NY and she said the humidity is worse than here!!
so that sounds pretty good considering the vafc/cam gears are untuned. You'll be able to hit mid 14s if you tune those and let the weather clear up. good job
